Embodiment
As shown in Figure 1; The ultra material radome 10 of the utility model comprises the rigid frame 20 and the ultra material sheet material 30 that can be fixed in said framework 20 surfaces of hollow, and shown in Fig. 1 is all right one way or the other ultra material sheet material 30 that is individually fixed in the two relative side of said framework 20.Said framework 20 is by processing like any current materials such as fiberglass, and it comprises a support body 22 that roughly takes the shape of the letter U and a microscler channel guide section 24 that is arranged at two elongated ends of said support body 22.The peripheral both sides of said support body 22 form a recessed groove 222 respectively.Said channel guide section 24 forms a guide groove 242.
As shown in Figures 2 and 3, each ultra material sheet material 30 comprises at least one ultra sheet of material 40.Each ultra sheet of material 40 comprise two medium substrates 42,44 that fit together and place said two medium substrates 42, between 44 and the structure sheaf 46 that covers by said two medium substrates 42,44.Said two medium substrates 42,44 can be processed by polymeric material, ceramic material, ferroelectric material, ferrite material, ferromagnetic material etc., and said two medium substrates 42,44 both can have been processed by commaterial, also can be processed by two kinds of material different respectively; Their thickness both can equate, also can be unequal.The lamella that two medium substrates 42,44 shown in Fig. 2 are made of the same material with equal thickness.
Please continue with reference to figure 3, said structure sheaf 46 comprises a plurality of metal micro structures 48, like the pattern that is separated to form by dotted line among the figure, is merely the part metals micro-structural 48 of said structure sheaf 46 shown in Fig. 3.We are called ultra material cell with each metal micro structure 48 and two medium substrates, 42,44 parts corresponding with it.Generally, the physical dimension of each ultra material cell is relevant with the electromagnetic wavelength that passes said ultra material radome 10, is 1/10th of electromagnetic wavelength like its physical dimension.Each metal micro structure 48 is the plane with certain geometrical shape or stereochemical structures that the metal wire sections by certain size constitutes, and wherein, the cross section of metal wire sections can be for flat or other arbitrary shapes, as cylindric.Metal micro structure 48 shown in Fig. 3 is the planar structures that are made up of the metal wire sections with flat cross section; And be and periodically arrange; Also promptly, said a plurality of metal micro structures 48 are periodically to be arranged in said two medium substrates 42, between 44, and to be covered by said two medium substrates 42,44.In the present embodiment, said a plurality of metal micro structures 48 are to be covered in forming like metal formings such as Copper Foils on the medium substrate 42 (or 44) through etching one, and then are covered with another medium substrate 44 (or 42) and said a plurality of metal micro structures 48 are covered and get final product.Certainly, said a plurality of metal micro structure 48 also can adopt plating, bore quarter, photoetching, electronics is carved or ion quarter etc. mode be formed on said medium substrate 42 or 44.
Metal micro structure 48 shown in Fig. 3 only is an embodiment who is used to illustrate, roughly is cross, and two relative metal wire sections of per two adjacent metal micro-structurals 48 are located along the same line and are provided with at interval.In the reality, said metal micro structure 48 can also be other arbitrary shapes as required.Dielectric constant and/or magnetic permeability that we utilize the geometry and the size of said metal micro structure 48 and arrange and change said ultra sheet of material 40; When making electromagnetic wave through said ultra sheet of material 40 less, the incident of loss and when leaving said ultra sheet of material 40 reflection few, thereby improve the ripple rate of passing through of said ultra sheet of material 40.This shows, even said ultra material sheet material 30 also has the higher ripple rate of passing through when being made up of the said ultra sheet of material 40 of multilayer.
Please continue with reference to figure 4; During assembling; Two surpass in the recessed groove 222 that material sheet material 30 places said support body 22 both sides respectively said; And utilize glue fixing on said framework 20, thereby form one be used to hold antenna cavity 26, and the guide groove 242 of said channel guide section 24 is connected with said cavity 26.At this moment, can said ultra material radome 10 be installed on the place that needs, antenna (figure does not show) be placed in the said cavity 26 protect.Like this; Said ultra material radome 10 is owing to the rigidity of said framework 20 has the favorable mechanical performance; And have a plurality of metal micro structures 48 owing to be covered in the ultra material sheet material 30 of said framework 20; Can reduce the electromagnetic loss that antenna is received and/or launches, also make it have superior wave penetrate capability.
In fact; Because the metal micro structure 48 in each ultra material sheet material 30 places said two medium substrates 42, is protected between 44; Can avoid the harmful effect of extraneous mal-condition; Not only can keep stable wave penetrate capability, and form fine and close structure owing to said two medium substrates 42,44 press together, its mechanical performance is also better.Particularly in order to satisfy diversified application demand needs and to make thicker ultra material radome 10, ultra sheet of material 40 pressings of available multilayer form said ultra material sheet material 30, and like this, its mechanical performance is more excellent.
In addition, said ultra material sheet material 30 can be formed by at least one medium substrate and the structure sheaf of being made up of a plurality of metal micro structures that is pressed together on the said medium substrate; And when said ultra material sheet material 30 comprised multilayer dielectricity substrate and multiple layer, multilayer dielectricity substrate and multiple layer were alternately stacked together.Certainly, the outermost of said ultra material sheet material 30 is covered by two medium substrates.
The above only is some specific embodiments of the utility model, should not constitute the restriction to the utility model.For those skilled in the art; Under the prerequisite that does not break away from the utility model basic thought; Can also make some improvement and retouching, also can process the lighter member of weight, with convenient carrying with install by light material like said framework 20 as required; Said ultra material sheet material 30 also can be made arbitrary shape or this is spliced into certain shape by the ultra material sheet material 30 of polylith according to the shape of said framework 20 and other needs, and these improvement and retouch the protection range that also should be regarded as the utility model.
